Faults
Faults are declared as either present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but have not been diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault
If the fault is not confirmed, check:
– the electrical connections that correspond to the fault,
– the connectors for this connection,
– the resistance of the component detected as faulty,
– the condition of the wires.
Refer to paragraphs 3.1 Checking the wiring and 3.2 Checking the connectors.
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
– carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
– check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints – Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints.
A summary of the overall procedure to follow is provided on the following page in the
form of a flow chart.

3. FAULT FINDING PROCEDURE (continued)
3.1 Checking the wiring
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the protectors, insulation, and routing of the wiring, as well as the mountings.
Tactile inspection
When manoeuvring the wiring, either use the diagnostic tool to detect a change in status, from "stored" to
"present", or the multimeter to view the status changes.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
Checking earth insulation
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the 12 V or 5V feed. The correct measured value is 0V.
Checking insulation against + 12 V or + 5 V
This check is carried out by measuring the voltage (multimeter in voltmeter mode) between the suspect connection
and the earth. In the first instance, the earth may be taken on the chassis. The correct measured value is 0V.
Continuity check
A continuity check is carried out by measuring the resistance (multimeter in ohmmeter mode), with the connectors
disconnected at both ends. The expected result is: 1Ω±1Ω for each connection. The line must be fully checked,
and the intermediate connections are only included in the method if this saves time during the fault finding
procedure. The continuity check on the multiplex lines must be carried out on both wires. The measured value
should be 1Ω±1Ω.
Checking the supply
This check may be carried out using a test light (21 W or 5W depending on the maximum authorised charge).

For Laguna II:
Brake pedal released
– continuity between connections 5A and SP13,
– infinite resistance between connections 65A and SP17.
Brake pedal depressed
– infinite resistance between connections 5A and SP13,
– continuity between connections 65A and AP10.
Replace the switch if necessary.
Check the condition of fuse H 15A on the passenger compartment fuse and relay board.
Replace the fuse if necessary.
Check the supplies to the switch:
For Mégane II and Scénic II:
+ 12 V after ignition Connection SP17 of component 160
+ 12 V battery Connection BPT of component 160 (via ABS)
For Laguna II:
+ 12 V after ignition Connection SP13 of component 160
+ 12 V battery Connection AP10 of component 160
Check the continuity and insulation of connection 5A between components 120 and 160.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
2.DEF
NOTESNone
Check the brake pedal switch connections.
Check the condition and adjustment of the brake pedal switch.
Repair if necessary.
Check the continuity and absence of interference resistance on connection 5A between components 120
and160.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the conformity of the switch by consulting the interpretation of statuses ET704 Brake switch no. 1 and
ET705 Brake switch no. 2.
If the fault is still present, run fault finding on the ABS computer (see 38C, Anti-lock braking system).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
